4 Claims. 1

An object of the present invention is to provide a machine for expediting'the operation of addressing envelopes, and has been found extremely useful in numerous lines of businesses where large numbers of letters, bills, and advertising matter are sent out periodically to the same addresses, for addressing the envelopes containing such material, and whereby considerable time may be saved in the operation of preparing such material for mailing. resulting in a corresponding decrease in the cost of doing the job.

Another object of the present invention is to provide a small, compact envelope-addressing machine having means for quickly shifting each address into position in the machine'so that the envelopes may be quickly successively fed into position beneath the pressure bar to receive their respective addresses.

A further object is to provide an addressing machine comprising a suitable tape upon which all of the addresses are typed, preferably in alphabetical order, and said tape being so mounted in the machine that the operator may readily manipulate the tape to successively advance the addresses into position in the machine in one direction, while the envelopes are successively fed into position over the tape in a direction at right angles to the travel of the tape, and

' pressed into address-receiving contact with the tape.

A further object is to provide in a machine of the class described, a simplified and inexpensive means for positively transferring a regulated quantity of printing fluid onto a surface of the face of each envelope, as the envelopes are successively fed through the moistening device, and whereby each envelope is moistened just enough to cause its wetted surface to receive a clearly defined imprint from the address on the master tape with which it comes in contact, and whereby the addresses imprintedv on said envelopes will have the appearance of being typed directly thereonto.

A further object is to provide a machine of the class described comprising a few moving parts and all of the moving parts thereof being of simple and-inexpensive construction, and so arranged as to facilitate manufacture and assembly thereof.

A further object is to provide a machine for addressing envelopes having means for readily and conveniently aligning the addresses with the travel path of the envelopes fed through the machine, whereby the addresses will be neatly and accurately placed bn their respectiv lopes.

A further object is to provide an envelope-addressing machine comprising an elongated tape having a plurality of addresses typed thereon in uniformly spaced relation lengthwise of the tape, and said tape being movable over a suitable platen having means for pressing each envelope into address-receiving contact with an address on the tape, as the envelopes are successively fed over the tape to receive their respective addresses.

Other objects of the invention reside in the novel construction of the means provided for controlling the application of the printing fluid onto the surface of the fluid transfer roll; in the simplified construction of the ink transfer roll and its complemental pressure roll which coact to moisten a portion of the face of each envelope with printing fluid, so that when the moistened surface of each envelope is subsequently pressed into contact with an address on the tape, it will receive an imprint from said address; in the provision of a machine of the character disclosed having a mirror positioned to reflect to the operator the position of each address advanced to the platen, and whereby each address as it is reflected in the mirror will show the address as it will subsequently appear on the envelope, whereby the operator may readily check each address before the envelopes are pressed into contact 'therewith; and in the provision of such an apparatus having means for facilitating the correction of addresses on the master tape, and whereby new addresses may readily and conveniently be added, when necessary, or a new address substituted for an old one, without requiring replacement of the master tape.

These and other objects of the invention and the means for their attainment will be more apparent from the following description taken in connection with the accompanying drawings.

In the accompanying drawings there has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown, as various changes may be made within the scope of the claims which follow.

Figurms a sectional plan view on the line 33 of Figure 4;

Figure 9 is a detail sectional view on the line 33 of Figure 3, showing the mounting of the rear tape-supporting spool;

Figure 10 is a plan view of the fluid tank, removed from the machine; and

Figure 11 is a perspective view of the fluid transfer roll and its support, removed from the tank.

The novel machine herein disclosed is shown comprising a frame I, generally U-shaped in cross section, and comprising a bottom wall 2 and spaced side walls 3 and 4. A horizontally disposed platen 5 is shown secured to the upper member 6 of a U-shaped bracket, generally designated by the numeral 1, and having spaced legs 8 and 9 shown secured to the side walls 3 and 4 of the frame I, by such means as screws or rivets II. The platen 5 provides a support for a portion of a master tape l2 upon which the addremes are applied or typed in properly spaced relation.

The master tape is in the form of a strip of paper of suitable width and length whereby addresses of individuals and firms may be typed thereon transversely of the tape, and spaced apart lengthwise of the tape, as illustrated in Figure 6. The addresses are typed on the paper tape with a strip of suitable carbon paper, the carbon side of said carbon paper facing the back of the tape so as to make a carbon impression in reversev on the back of the tape, when the addresses are typed onto the master tape in a conventional typewriter. The carbon material used is such as to be readily transferable from the master tape onto the moistened faces of the envelopes, as each envelope is momentarily pressed into contact with an address on the master tape, as will be later described.

The tape with the addresses applied thereto is wound upon a spool l3 comprising end plates or disks I 4 which may be secured to the ends of the spool by suitable nails or other fastening elements, not shown inthe drawings. Pivot pins II are secured to the ends of the spool adapted to be detachably received in open ended slots or bearings 16 provided in the upright edges of the side walls 3 and 4, as clearly illustrated in Figures 1 and 2, and whereby the spool of tape may readily be inserted into the machine or be removed therefrom.

The opposite or free end of the tape is formed with a reduced tongue I! adapted to be received in a slot l3 provided in a spool IS. The spool I3 is mounted in the rear portion of the frame l and is manually rotatable by manipulation of a crank 2| to wind the addressed portion of the tape thereon from the spool l3, it being understood'that the inner end of the tape which is in, direct contact with the spool I3 is not unwound from the spool, as may be understood by reference to Figure 6.

Disks 22 are secured to the ends of the spool l8 to guide the tape thereonto, and suitable trunnions or pivot pins 23 and 24 are also secured to the ends of the spool. The pivot pin 24 is shown extending outwardly beyond the side wall 3 and has a spring 20 interposed between its head 26 and the frame wall 3 to impose a slight friction on the spool 19 to prevent it from overrunning, when the tape is longitudinally moved by manual manipulation of the spool I3, as will subsequently be described.

An important feature of the present inven tion resides in the means provided for moistening the front face of each envelope just prior to being delivered into position over the tape to receive an address. To thus moisten the envelopes, each envelope is passed between a spring-actuated pressure roll 21 and a fluid transfer roll 23, best shown in Figure 4. The pressure roll 21 is mounted in a bracket 29 which overhangs the path of travel of the envelopes and is shown having a depending leg 3| securedto the back wall 32 of a laterally extending frame portion 33, by such means as bolts 34.

The laterally extending frame portion 33 is preferably constructed of sheet metal, formed to provide a box-like structure having one end secured to the side wall 3 of the main frame I by suitable means such as welding. The frame extension 33 is open at its top and bottom, and a fluid tank 35 is mounted in the upper portion thereof and has its intermediate portion supported on a partition 36 having its ends secured to the back and front walls 32 and 31, respectively, of the frame extension 33.

A'suitable resilient element 38 may be interposed between the upper edge of the partition 35 and the bottom wall of the tank 35 to cushion the tank on the partition as will be understood. When the tank is in position in the machine, its right hand end 39, when-viewed as shown in Figure 4, may abuttingly engage one of the screws II, as shown in Figure 4, to limit movement of the tank in that direction. The opposite end 40 of the tank projects through a notch 4| provided in the end wall 42 of the frame extension 33, as illustrated in Figures 1 and 4. The overall length of the tank 35 is such that its end 40 projects beyond the end wall 42 of the machine frame, whereby fluid may conveniently be introduced into the tank through its Projecting open end. I v

The side walls 43 and 44 of the tank 35 are notched, as shown in Figure 4, whereby the end 40 of the tank is reduced in height and projects outwardly from the notch in the end wall 42 of the machine frame, as herelnbefore stated.

The tank 35 is retained in position in the machine frame by a top plate 45 which provides a closure for the open top of the frame extension 33, and also the tank 35. The plate 45 has 9. depending flange 46 at one end which abuttingly engages the vertical edges 41 of the side walls of the tank to thereby retain the tank in position within the frame extension 33.

The top plate 45 also has 9. depending flange 43 seated against the outer surface of the front 1 wall 31, as shown in'Figure 1, and suitable screws 48 detachably secure For convenience, the fluid transfer roll 28 may be rotatably supported in a U-shaped bracket 59 shaped to fit into one end of the tank 35, as shown in Figures 4 and 10. The fiuid transfer roll is vertically aligned with the pressure roll 21, and projects through the opening 52 in the top plate 45, whereby it may engage each envelope passed over the plate 45 to thereby moisten a portion of the face of each envelope.

The top plate 45 also has a relatively larger opening 54 therein through which the portion of the master tape supported on the platen is exposed to the envelopes. In other words, the opening 54 is aligned with the path of travel of the tape, indicated by the arrow 55 in Figure 8.

The side portions 56 and 51 of the plate 45 terminate at the right hand end of the machine in a depending flange 58, seated against the outer surface of the side wall 4 and preferably secured thereto by one of the screws or bolts l I. The guide flange 5! extends the full length of the plate 45 whereby the envelopes may be guided by said flange the length of their travel through, the machine.

The platen or tape supporting plate 5 is disposed lengthwise of the opening 54 and is located in fixed relation to the guide flange 5| whereby theaddresses applied to the envelopes will always be uniformly spaced from the bottom edges of the envelopes, provided, of course, that the addresses on the tape are brought into correct registry with the opening 54. The top. surface of the platen is disposed slightly below the top surface of the plate 45, as shown in Figure 4, whereby the instant the operator releases the operating handle of the machine, the addressed envelope will move out of engagement with the master tape l2, thus preventing smearing of the ink on the face of the envelope.

Another important feature of the invention resides in the means provided for controlling the amount of moistening fluid transferred onto the face of each envelope by the periphery of the fluid transfer roll 28, each time an envelope is passed through the machine to receive an address. In other words, it is highly desirable that the face of each envelope be moistened just enough to cause its moistened surface to receive just enough ink from the master tape, when subsequently pressed into address-receiving contact therewith, to receive a sharply defined impression from the address on the master tape 12 without danger of the inksmearing.

To control the amount of fluid transferred onto the surface of each envelope, a bar 6|, preferably of metal, is provided in the tank 35, and its length is such that when its pointed terminal 82 engages the end wall 48 of the tank, its opposite end 63 will be supported against the periphery of the fluid transfer roll 28, as shown in Figure 4. An absorbent wiping element 64 is fitted around the end 83 of the bar 6! and may be secured thereto by suitable means such as a asoanes 6 staple 85. The absorbent element 84 has an end portion 55 depending into the fluid in the bottom of the tank. The element 64 wipes the excess fluid from the periphery of the roll 28 and allows just enough fluid to adhere thereto to adequately moisten each envelope. This is an extremely important feature of the invention, as it prevents over-moistening of the envelopes, which might result in a smudged impression on the face of an envelope.

By reference to Figure 4, it will be noted that only a small amount of fluid is normally contained in the tank 35, whereby only the lower peripheral portion of the fluid transfer roll 28 is submerged in the fluid. Should the fluid level drop to a level below the lowermost part of the roll 28, whereby the periphery of the roll would not contact the fluid, then the depending portion 56 of the fluid absorbent wiping element 54 may act as a wick to temporarily supply fluid to the periphery of the fluid transfer roll until the supply of printing fluid in the tank has been replenished. Under normal operating conditions the element 63 serves only as a wiping element to prevent an oversupply of fluid being transferred onto the envelopes by the fluid transfer roll 28.

The pressure roll 2'! is removably supported in the bracket 29 which, it will be noted by reference to Figures 1 and 4, has its upper portion overhanging the table top or plate 45, whereby the pressure roll 21 is supported directly over the fluid transfer roll 28, as hereinbefore stated. The pressure roll 21 is normally held in yieldable contact with the periphery of the roll 28 by suitable springs 61, interposed between the upper horizontal portion 58 0f the bracket 29, and shoulders 59 provided on upright pressure bars "H, having their lower ends forked and engaged with the shaft 12 of the pressure roll 21. The terminals of the shaft I2 are reduced in diameter and are rotatably received in slots 13 provided in the bracket 29, whereby the shaft 12 is adapted for limited vertical movement in the bracket 29.

The pressure bars II are disposed in opposed relation, as best illustrated in Figure 2, and cooperate to constantly exert a downward pressure upon the roll 21 because of the springs 61. Thus, as each envelope is fed between the rolls 21 and 28, the portion of the face of each envelope engaging the moistened surface of the fluid transfer roll 28 will be be held firmly in contact with the periphery of said roll to assure uniform moistening of the face of each envelope, which is essential in order to produce work of uniform quality.

Another important feature of this invention resides in the manner in which the envelopes are successively fed into position over the tape to re ceive an address. By referring to Figures 1 and 4, it will be noted by reference to the arrow 14, that the envelopes are fed over the tape in a direction at substantially right angles to the direction of the travel of the tape. This has been found extremely desirable in the operation of the machine, as it makes it possible for an operator to conveniently shift the master tape from one address to the next with one hand, and with bar I5, shown having upturned end portions 16 V and I1 pivotally supportedon a shaft 18 mounted in the spaced members 19 of a suitable operatin handle, generally designated by the numeral 88. ,The spaced members 19 of the operating handle are pivotally mounted on a cross shaft 86, sup ported in the spaced legs 88 and 84 of an inverted U-shaped bracket, generally designated by the numeral 82. Th spaced legs 83 and 84 of the bracket 82 are shown seated against the outer surfaces of-the side walls 8 and 4 of the machine frame, as will be noted by reference to Figure 8. The leg 84 preferably extends to the bottom of the machine frame, whereas the leg 83 may terminate at a higher elevation, as indicated by the dotted line 85 in Figure 2.

Suitable tortion springs 81 are coiled about the shaft 86 adjacent the ends thereof and each has one end anchored to a-piate 88. The opposite ends of the springs 81 are received in apertures 89 provided in the side members 19 of the operating handle 8|, as shown in Figures 2 and 3, whereby said springs cooperate to support the handle in its normal elevated position, shown in Figure 2.

To cause the pressure bar 15 to follow substantially a straight path in its up and down travel, a link 9[ is shown having one end pivoted to the leg 83 of the U-shaped bracket 82, and its opposite end to the upright leg 1'6 of the pressure bar 15. The link 9| is disposed in parallel relation to the adjacent side member I9 of the operating handle, whereby the pressure bar is always retained in operative relation to the platen and the envelope fed over. the tape to receive an address. A suitable cushion pad 92 is preferably secured to the bottom face of the pressure bar I5 adapted to directly engage the envelope and exert a squeezing pressure thereon, when the operating handle is manipulated to press an envelope into address-receiving contact with the tape.

Another important feature of the invention resides in the provision of means whereby the operator may carefully check each address as it is,

.brought into place beneath the pressure plate to assure him that the name of each addressee and his address are correctly spelled, and also that the addresses will be properly positioned upon the envelopes.

The means provided whereby the operator may thus conveniently view each address, as it is advanced into position over the platen 5, is best shown in Figure 2, and comprises a mirror 93 secured to the lower marginal edge portion of the plate 88 and disposed at the proper angle with respect to the operators eyes, whereby each address as it is moved into position beneath the pressure bar I5, will be reflected in the mirror 83 so that the operator may conveniently view each address as it moves into position over the platen. In Figure 2, the broken line 94 indicates th reflection of the address into the mirror, and the broken line 95, the operators line of vision.

A pair of spring clips or fingers 95 have their end portions 90 secured to the bottom side of the portion 51 of the top plate 45, and extend across the opening 54 at each end thereof with their opposite ends disposed beneath the plate portion 56, as clearly illustrated in Figure 8.

The spring fingers 95 are disposed over the marginal edge portions of themaster tap l2, and function to hold said edge portions in contact with the platen 5, as will be understood. The shaded area 91 on each spring finger 98 may be colored. red, or some other bright color, to facilitate aligning each address with the platen.

8 In other words, each address moved into position over the platen 5 must be substantially aligned with the colored areas 91 to assur correct and uniform placement of the addresses upon the faces of the envelopes.

To prevent the tape spool l8 from overrunning when the crank 2| of the spool I9 is manipulated to wind the tape onto the spool l9, to prepare the machine for operation, suitable springs 98 are shownsecured to the inner surfaces of the side walls 3 and 4 of the machine frame and have their free ends frictionally engaging the disks I4 to thereby prevent the spool from overrunning, as will be understood by reference to Figures 5 and 8.

Means is also provided to facilitate making corrections on the master tape, in the event that it becomes necessary to change an address, or in the event that the name and address of a firm or individual is to be removed from the mailing list.

To make such corrections on the tape, a strip of correction labels, shown at 99 in Figure 7, is divided into a plurality of labels IOI by lines of perforations I82, whereby the labels may readily be successively torn from the strip 99, as required. When a new address is to be substituted for one already on the master tape I2, the new address is typed onto the end label of the strip 99, as shown in Figure '7, and the typed label is then tornfrom the strip 99 and placed over the address on the master tape which is to be deleted or removed therefrom. The labels are gummed on one side so that they may readily and quickly be secured to the master tape.

In the operation of the novel envelope addres-, sing machine herein disclosed, the envelopes to be addressed may be placed in a stack on a table adjacent to the addressing machine, and the master tape is then positioned in the machine and its free end inserted in the slot l8 provided in the rear spool l9. The spool i9 is then ro-, tated by manipulation of the crank 2| to wind, the master tape onto said spool, until the last tioned over the platen 5.

The addresses may be placed in any desired order upon the master tape, depending upon the order in which the envelopes are to be addressed. It has been found very practical, however, to arrange the list of addresses alphabetically on the tape with blank spaces being left between the letters of the alphabet for the insertion of additional names, when necessary, When applying or typing the addresses onto the tape, the A names are typed onto or adjacent to the end of the tape which is wound directly onto the spool l3. Then when the typed tape is wound onto the rear spool I9, as hereinbefore stated,

the A addresses are first brought into position' upon the platen 5 in the order in which they are' typed on the tape, and thereafter the B addresses, etc.

When the first A address has been brought into position over the platen, the operator grasps an'envelope with his left hand and places it on the plate 45 against the guide 5|, and then moves it along the plate between the moistening rolls 21 and 28 and into position over the address.

positioned on the platen. The operator then with his right hand manipulates the lever 8| to move;

the pad 92 of the pressure bar 15 into engagement with the envelope whereby the moistened surface of the envelope is pressed into address- 9 grasp on the lever II, he engages one of the pro- Jections Hill of one of the disks ll of the spool I I, and rotates said spool in the direction indicated by the arrow in Figure 1, whereby the tape is advanced in the direction of the arrows ii to position the next following address over the platen 5. It will thus be seen that an operator may quickly and conveniently feed the envelopes through the machine with one hand, and with his other hand manipulate the operating lever II and the master tape II, as above described.

By reference to Figures 1 and 8, it will be noted, as hereinbefore stated, that the envelopes are fed into position beneath the pressure bar II in a direction at right angles to the directional movement of the master tape.

The spring pressure applied to the pressure roll 21 is comparatively light but is sufficient to hold each envelope in peripheral contact with the fluid transfer roll 28 to assure that the face of each envelope will be moistened sumciently to receive a clearly defined impression, when pressed into address-receiving contact with the tape II. By feeding the envelopes into the machine as above described, the operation of the machine may be greatly expedited, as the operator may readily shift the tape from one address to the next with one hand while he moves an envelope into position over the platen I with his other hand.

The machine is very simple and inexpensive in construction, and the parts are so arranged as to facilitate assembling the parts, and also whereby the machine may readily be disassembled, if necessary, to facilitate making repairs or for cleaning. The parts are also so constructed and arranged that the machine readily lends itself for manufacture in quantity production -at low cost.

In the specification and accompanying drawings, a manually operable machine has been disclosed, wherein the tape is manually manipulated to intermittently advance the addresses into position over the platen I. It is to be understood. however, that if desired, means not shown may be provided for automatically advancing the master tape from one address to the next, each time the operating lever 8| is depressed to press an envelope into address-receiving position with the tape.

It will be apparent to those skilled in the art that I have accomplished at least the principal objects of my invention, and it will also be apparent to those skilled in the art that the embodiments herein described may be variously changed and modified without departing from the spirit of the invention, and that the invention is capable of uses and has advantages not herein specifically described; hence it will be appreciated that the herein disclosed embodiments are illustrative only, and that my invention is not limited thereto.
